Linux Distros Unpatched Vulnerability : CVE-2026-19395

high Nessus Plugin ID 362998

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- In Qt for MCUs, a Text element that displays styled text halts the device if an <img> tag in the text contains an attribute with an empty value. The text parser passes the empty value to an internal check that only accepts non-empty values. The check fails and reports an error, and the default error handler halts the device. (CVE-2026-19395)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
